Object class superclass superclass superclass superclass superclass = Object

evaluates to true :)
enclosing a picture that helped me understand - except Squeak/Cuis have ProtoObject between Object and the top of the hierarchy (i.e. nil)

Clases are objects… therefore they answer all the Object protocol.
Class subclasses ClassDescription that subclasses Behavior that is a subclass of object
The smalltalk meta model is spectacular

Hi,

I've just realized a class (in the Object hierarchy) understand instance side messages from the Object hierarchy?

I expected a DNU error.
